Key Features
2500V-RMS Galvanic Isolation:
Creates a safe barrier between two I2C bus sides, preventing electrical noise and transient spikes (e.g., from motors, power supplies) from affecting signal integrity.
Suitable for isolating grounded controllers from ungrounded devices or separating high/low voltage domains.
High-Performance Communication:
Supports I2C clock rates up to 1MHz with full bidirectional data flow and clock stretching, compatible with standard, fast, and fast-mode plus I2C devices.
Open-drain architecture on both sides allows flexible voltage translation (3V–5.5V) for mixed-voltage systems.
Plug-and-Play Connectivity:
Dual STEMMA QT/Qwiic connectors enable quick, solderless integration with SparkFun Qwiic-compatible boards, sensors, and cables.
Breakout pads for power (VCC), ground (GND), clock (SCL), and data (SDA) on both isolated sides for direct wiring if needed.
Rugged Design for Harsh Environments:
ESD Protection: 4kV HBM on all pins (8kV on bus pins) safeguards against electrostatic discharge during handling and operation.
Transient Immunity: ±50kV/μs typical common-mode transient rejection prevents interference from high-speed voltage spikes.
Wide Temperature Range: Operates reliably from -40°C to +125°C, suitable for industrial, automotive, and outdoor applications.
